A known power source (S) comprises input (G1, T) and output (G2, T) converting components with LT and MT converting cells (CC), T >/= 0 galvanodecoupling bifilar converter transformers (GTR) (2, 9, 12, 16, 20, 22, 24, 26 ,29). Lo >/= 2, Mo >/= 2 CC are based on "Motovilov's transformers" and on direct current power transformers (TM), each comprising two symmetrical groups of windings and rectifiers, in particular, for pulse control of the direct current of the windings of TM. To decrease the influence of the pulse and alternating current in the windings of TM and GTR on leakage inductance Ls of the windings, and to consequently improve the frequency qualities of S, the decoupling and converting functions in S are distributed between GTR with a gain factor of 1, having correspondingly reduced Ls, and the TMs introduced for that purpose into the converting components (G11 and G21) intended to function on direct current (2, 9, 22, 24, 29) whereas Lo and Mo of CC with TM functioning on the basis of direct current are interconnected according to a multicell circuit which is characterized by the number of voltage levels at the output of the circuit equal to Y = 1 + 2<L(M)> at the total power of all CCs equal to P < 2P1, where P1 is the power of the first CC, and which is intended for smooth control of the output voltage of S without the pulse current at the output of S and in TM. Additionally is also proposed connection L1 >/= 2 and M1 >/= 2 of CC according to said multicell circuit (12, 16). |
